The communication and power supply interface circuit is simple in structure, saves manpower and material resources, and improves the work efficiency.
Description
Technical field
The utility model relates to the interfacing field, and particularly a kind of transmitter communication and power supply interface circuit are applicable to transmitter.
Background technology
Existing 4～20mA two-wire system transformer utilizes the USB physical interface of certain specification, is used for realizing single data communication between PC and the transmitter, does not utilize this interface realization to the power supply of equipment, and power supply is normally introduced from 2 connection terminals.In the detection and production test calibration process of equipment, need on connection terminal, repeatedly connect and remove 2 external power supply lead-in wires, demarcate for Equipment Inspection and production test and bring very big inconvenience.If utilize existing interface to realize data communication and two kinds of functions of power supply supply, connected communication line at every turn when inserting interface and power supply is provided, will save the trouble that connects 2 external power supply lead-in wires and remove afterwards at connection terminal.
The utility model content
In view of this, the purpose of this utility model provides a kind of transmitter communication and power supply interface circuit, and when can realize inserting equipment interface, not only having connected communication line also provides power supply at every turn.
The utility model adopts following scheme to realize: a kind of transmitter communication and power supply interface circuit, comprise the standard physical interface that is applied on the transmitter, it is characterized in that: described standard physical interface is provided with in order to form two power pins of an insulating power supply.
In the utility model one embodiment, described standard physical interface is USB interface or 1394 interfaces.
In the utility model one embodiment, one of them links to each other the grounding pin GND of described standard physical interface and described two power pins.
In the utility model one embodiment, putting in order of described each pin of USB interface is: the anodal V+ of insulating power supply, transmission data TXD, reception data RXD, the negative pole V-of insulating power supply and the grounding pin GND that is connected with interface hull or cable shield.
In the utility model one embodiment, putting in order of described each pin of USB interface is: the anodal V+ of insulating power supply, transmission data TXD, reception data RXD, unsettled pin, the negative pole V-of insulating power supply and the grounding pin GND that is connected with interface hull or cable shield.
In the utility model one embodiment, the transmission data TXD in the described pin arrangements order and reception data RXD exchange.
The utility model can solve existing equipment in detection and production test calibration process, need on connection terminal, repeatedly connect and remove the inconvenience that 2 external power supply lead-in wires bring, connected communication line and power supply is provided when can realize inserting interface at every turn, circuit structure is simple, save human and material resources, improved work efficiency.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Present embodiment provides a kind of transmitter communication and power supply interface circuit, comprises the standard physical interface that is applied on the transmitter, it is characterized in that: described standard physical interface is provided with in order to form two power pins of an insulating power supply.
Table one is the pinout of USB:
Table one
Present embodiment, be under the constant situation of above-mentioned existing physical interface, the pin of interface is redefined, see also Fig. 1, Fig. 1 is the pin connection diagram of the utility model USB interface, is disposed with V+, TXD, RXD, V-and GND among Fig. 1 from top to bottom.Here put in order not as restriction; In a word, this interface is provided with 5 pins, 2 positive pole and negative poles that pinout is insulating power supply wherein, and 2 pinouts are data communication, another pinout is communication ground connection.For consistent with arranging of present Universal USB interface and cable, adopt the pinout after the above-mentioned change especially; Wherein pin 1 is defined as the anodal V+ of insulating power supply, pin 2 and pin 3 are defined as and send data TXD and receive data RXD, pin 4 is defined as the negative pole V-of insulating power supply, pin 5 is that interface hull or cable shield are defined as communication ground connection, thereby consistent with the definition of Universal USB cable, saved cable cost customized.
In another embodiment of the utility model, see also Fig. 2, described USB interface also possesses a unsettled pin, and its pin arrangements is in proper order: the anodal V+ of insulating power supply, transmission data TXD, reception data RXD, unsettled pin, the negative pole V-of insulating power supply and the grounding pin GND that is connected with interface hull or cable shield; Here put in order not as restriction.This USB interface can be Mini-USB or Micro-USB interface.Describe with the Mini-USB interface below:
Table two is pinouts of Mini-USB or Micro-USB:
Table two
Present embodiment is under the constant situation of above-mentioned existing physical interface, and the pin of incoming end is redefined, and this is disposed with V+, TXD, RXD, unsettled pin, V-and GND from top to bottom.Please continue referring to Fig. 2, pin 1 is defined as the anodal V+ of insulating power supply among the figure, pin 2 and pin 3 are defined as and send data TXD and receive data RXD, pin 4 is unsettled, pin 5 is defined as the negative pole V-of insulating power supply, pin 6 is that interface hull or cable shield are defined as communication ground connection, thereby consistent with general Mini-USB cable definition, has saved cable cost customized.
What deserves to be mentioned is that the sortord of above-mentioned pin is not limited in this, the transmission data TXD in those pin arrangements orders and reception data RXD can exchange.The utility model can also satisfy the purpose that a bite is used more to power devices when utilizing USB interface and cable to realize data communication, simplifies technological process than current device, reduces production costs.
Be noted that foregoing is based on realizing on the USB interface, still also can looking equipment use interface difference and difference based on other interface, but must possess the requirement of the technical program on the pin.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
